This weekend things went a bit crazy for me. I am a happily married 39 year old soldier residing in Northern Ireland (Wife Nikki) and I gave into an urge I shouldn't have at the weekend. I took a big risk; luckily for me Diane is only interested in one thing. For the last few months Diane our 40 something next door neighbour married with three kids to Kevin (bit of a boring bastard, carpet salesman) has been spending a lot of time chatting with my wife, we have always had a good relationship with them both, they have looked after our kids and vice versa for example. About two months ago I noticed that when I got home on a Friday nights (I work in England during the week) Diane would be in our living room chatting with Madeline and her dress sense was becoming increasingly more and more inappropriate for her age, I hadn’t really noticed but Nikki pointed it out a couple of weeks ago when Diane left. I said to Nikki that I hadn’t really noticed, however I had, my wife is quite innocent and takes me at my word, I had settled down after meeting Nikki but of late I can’t help thinking about other women. Diane is in fairly good shape for her age, better shape than me anyway, I hadn’t really thought about her in a sexual way before as my kids think of her as an Aunt, but that was getting hard to do, she was wearing a mini skirt, leggings and knee high boots tonight. She was putting out signals but I am out of practice and I hadn’t noticed. I asked Nikki why Diane was spending so much time in our House, she said she is having problems dealing with not having her kids to look after now they are all at school, plus she has no real work skills and is finding it hard to get a job. Nikki told me that Diane was going to watch the kids while I dropped her off in Town for her Office Party Christmas Drinks later tonight. Nikki went upstairs to get ready for the party while I made something to eat, at about 6.30pm I opened the back door to put some rubbish in the Bin and I noticed through the fence into Diane's conservatory she was rowing with Kevin, it seemed like he was the way Diane was dressed, things got louder and Kevin stormed out of the house. I shouted up to Nikki and told her that Kevin and Diane were rowing; she said she knew as she could hear them through the walls. I’ll check and see if she is still ok to babysit later, so I went and knocked on the front door to confirm what time she would be in. When she opened the door I noticed that she seemed fine and was showing no sign of being upset, I asked her was she still on for tonight and she replied absolutely positively, which at the time struck me as a bit over eager, again everything was going over my head. She said I’ll see you later then and closed the door. I went back into the house and had my dinner and fell asleep in front of the TV, I was awoken about 7.45pm by Nikki saying she was ready and that the kids were fast asleep. I sent Diane a text message and said Nikki was ready to go, a couple of minutes later Diane knocked the door and came in, she had changed her clothing again, she looked quite stunning in her slouching clothes a loose sweater and washed out jeans, she had no makeup on at all and I noticed how well she looked without it, I commented on how well she looked and she gave me a smile and said thank you for the all too rare compliment. I said I would be back in ten to fifteen minutes once I had dropped Nikki off. I asked how Kevin and the kids where she said he had taken the kids to his Mums for the weekend and would be back on Sunday, she said she needed the break as things were getting on top of her. I said I'll be back in ten and she can get away and relax. I left to drop Nikki off in town, on the way down Nikki said she was a bit worried about Diane, she told me that Diane had confided in her and that things were at breaking point in her marriage, I said oh great that all I need when I get back is her chewing my ear, she is a nice lady but she can talk for Ireland and she is hard to shake off. Nikki said I was nasty and I should just listen to her for a while and make my excuses that I have work to do or something, I dropped Nikki off at about 8.15pm traffic in Belfast this time of year is a nightmare, Christmas shoppers! I got back to the house at about 8.45pm and opened the door and went straight into the Kitchen saying hi as I passed Diane in the living room, she followed me out into the Kitchen and asked did Nikki get dropped off and commented on how gorgeous she looked before going out, I hadn't really noticed as for some reason all I could think about was Diane sitting in our living room waiting on me getting back to the house, I said she always looked great and I was a lucky man, Diane said your both very lucky to have each other and said that the kids hadn’t made a peep and that she was off back home to get a nice long bath and an early night, I asked her if she wanted a coffee or tea before leaving she thanked me but declined. I checked in on the kids and they were sound asleep, so I settled down for a night in front of the telly, thank god it was Friday and no X Factor to put up with. Around 10.00pm Nikki rang to see how I was and ask about the kids, I said everything was fine and she should go and enjoy herself, she doesn’t get out very often so she should let her hair down, she said she would and said she will make me happy when she gets in at about 2.30 am. I always look forward to drunken sex with Nikki, she is really relaxed and it’s the only time I get some anal play. At about 10.30pm I got a text from Diane, saying she was bored and was the offer of a coffee still on, I could hardly say no, so I said sure pop in I’ll put the kettle on. A minute later the bell rang and in she came, she was just out of the bath in her pyjamas and housecoat and annoying fluffy slippers. Her face was all flushed from the hot bath and she moaned about the heat as we waited for the kettle. She removed her house coat and draped it over the dining room chair, I gave her the coffee and she thanked me and got up to walk into the living room, I followed her in and we sat on opposite couches, I was feeling a little uncomfortable and Diane had noticed. She asked was I alright I said I was fine just a bit stressed after a hard week, with the security issues in Ireland I had never told my neighbours what I do, Diane asked me what I did and I told her I was a soldier to which she said she had suspected that I was commenting on how fit I am and the amount of Phys that I do, she said she wished Kevin was a bit more active and that he was slowing down in more ways than one, I laughed and said that I had no complaints from Nikki, to which she replied she knew, she said her and Nikki were closer than I and Kevin new and they shared a lot more than I thought, I got a little embarrassed and Diane said one thing your not is shy so don’t come that with me. Diane asked me if she could ask me a personal question, awkwardly I said sure, She asked if I thought she was attractive, I said of course you are especially when you’re like you are now with no makeup or trashy clothes. She said she didn’t like the trashy clothes and makeup but said she was wearing them to get some attention, I said I like women the way you look now, natural, and she smiled and said that I was sweet. I said that it was my turn to ask her a question, I asked when the last time she felt good about herself was, and she said I am feeling a lot better having had this chat with you. I said I was interested in finding out what details Nikki and Diane had shared, she said that it was mostly about mine and Nikki's sex life as hers had gone off the boil, I said that was a shame as all marriages need a healthy sex life, she agreed. I asked Diane if she would like a glass of wine as she didn’t seem to have any intention of leaving in the short term, she bounced and said yippee that would be great, I opened a bottle of Rose and poured us both a glass. A few minutes later Diane told me that she hadn’t told Nikki but she had never had an orgasm and was wondering if there was something wrong with her, she said she told Nikki she had them all the time but that was a lie. I told her that there was nothing wrong with her just that a lot of women need a little mechanical assistance and that Nikki used a vibrator. Diane said she had thought about it but never had the courage to buy one and that Kevin never would. She said I would love to know what an orgasm was like. I said that she could borrow one of the ones we had never used when she left and she giggled and said she couldn’t believe I was so relaxed about these things. I said that sex is to be enjoyed not dreaded. She agreed and said she wished Kevin was more like me. We polished off the rest of the bottle of wine and I asked if she wanted to open another, she said yes please so I obliged. After another couple of glasses the conversation got more intense she started asking about the things I liked to do in the bedroom, I told her that my favourite was Anal, Diane looked surprised and said that Kevin was only into plain missionary sex, she was getting a little tipsy and was unaware that her pyjama top was riding up and I could see hear belly, it looked hard and I commented on how fit she was, she smiled at me again and told me that I was flirting with her, I said I wasn’t I just couldn’t help but see, she liked the fact I was noticing her and I could see her nipples starting to become erect under her bra and top, I asked her if she was cold and she blushed, I said now who's the shy one, she said she wasn't shy just not as confident as she used to be. I told her that she should try and take charge in the bedroom and force things on herself, she said that she would try and asked me if she could borrow the toy I mentioned earlier. I said its upstairs I’ll get it. I went to walk up the stairs and Diane was up right behind me, I said nothing as she followed me into our Bedroom. She asked to see it, I opened my bottom drawer and she gasped when she seen the contents, there are various dildos and vibrators and lubricants etc in there, I told her she should get a bottom drawer like ours and things will pick up. She sat on the bed and said that she was feeling a bit funny and could she lie down for a minute I said of course and she lay down, she fell asleep almost straight away and I left her thinking how am I going to explain this to Nikki when she gets in, I left the room and started downstairs and Diane woke and said not to leave her alone so I went back in. She rolled over and looked at me and said that she had fancied me for ages and that her sex life was in the doldrums because she thought of me while she was having sex with Kevin, I said that she was being silly as she was a little drunk. She said she knew she was a little drunk but had been thinking about my cock all night, she said that Nikki had told her that I had a nice cock that it was the biggest she had ever had, she asked if she could see it. I was a little drunk myself and had been turned on since seeing her flat stomach, I said I would show her it but I would need some insurance to stop her from spilling the beans to Nikki and Kevin, she asked what I would suggest. I said that If I took a couple of intimate pictures of her for my personal collection that would be my leverage against her spilling the beans, she said that would be fine so long as they remained private, we both knew this was going a lot further than just showing her my cock. I got my Video Camera out and set it up at the end of the bed and I asked her to remove her pyjamas, she slowly un buttoned her top as I snapped away, her Bra dropped away revealing a quite sensational pair of large breasts, she later told me she was a 30(G). I took a few more pictures and told her that would do. She said great now can I see your cock, I walked towards her and she reached out and unfastened my belt, she could see my bulge and she looked up at me and asked if she turned me on, I moaned as she reached into my shorts and curled her hand around my now engorged shaft, she gasped at my size and said that it was just as Nikki had described it. She stood up and whispered into my ear that she was here for me and that I could do whatever I liked to her. I told her to kneel down as I removed my trousers and shirt I told her to start sucking my cock, she needed a little coaching but her enthusiasm was amazing, she worked my cock into frenzy. She looked up at me and asked how she was doing I said that she was doing just fine, after a few minutes she stopped, stood up pulled down her pyjamas and knickers to reveal the most smooth pussy I had ever seen. I beckoned her onto the bed and asked her what she would like, she nodded towards the draw and asked what the big black 'feeldoe' vibrator was for, and I told her that Nikki liked to be fucked with it while sucking on my cock and Nikki has a black cock fantasy I told her. She said she wanted whatever Nikki gets so I put my hand between her thighs and started to work my fingers around her tight wet pussy, I got the dildo and started to spread her pussy lips wide with it, she moaned as it stretched her open and she began to move her hips downward, she moaned that she had never been so turned on, I whispered back that she should wait until my cock was buried deep in her arse with the dildo hanging out of her pussy, her eyes rolled back and she cried out. I spun Diane around so she was lying with her head over the edge of the bed, I pulled her hand down toward the dildo and she took over, fucking herself frantically while I placed my cock into her mouth, her tongue frantically licking my shaft. I reached into the drawer and pulled out a ten inch glass dildo and I told Diane to move into a doggy style position. I told her she was to continue fucking her pussy, I moved around to the other side of the bed and started to ease open her ass, she was tense but eventually relaxed and the glass cock started to slide in and out gently teasing her ass open, I could sense she was starting to struggle with the intensity and I rolled her onto her back, she looked up at me and said that she was having a great time and couldn’t wait to feel my cock inside her. So I pulled her to the edge of the bed and pulled her legs up over her shoulders and slid my cock inside her swollen pussy, she started to moan and thrust her hips against mine I was ready to come and she knew it, I pulled out and reached into the draw for Nikkis Magic Wand, I looked at Diane and said this is what will give you your first orgasm. I move Diane to the bottom of the bed and she lay face down with her ass in the air, I placed the tip of my cock inside her Ass and told her to push back until she couldn’t take anymore, she took all 7 inches balls deep and was really starting to enjoy the sensation, her moaning was getting louder and louder and I was afraid the kids would awaken. God knows what they would have made of it if they had disturbed us. I placed the wand against her clit and she immediately began to jerk violently, I rolled over onto my back with Diane know in the reverse cow girl with my cock buried deep in her ass, she took the wand and began to thrash it violently against her pussy bouncing frantically up and down on my cock, the sight of her breasts bouncing around in the mirror was breathtaking, thank god the camera was still rolling! After a couple of minutes she began to tense up and I could sense that her orgasm was welling up inside her, she stopped bouncing on my cock as her body went stiff and she cried out that she was cumming, her orgasm lasted for about five minutes. I just lay there waiting for her to stop tensing up; the sensation of her ass squeezed tight around my cock was toe curlingly good. She turned and looked at me and said she had never felt anything like it in her life and asked me if there was anything I wanted in return. I told her that one thing Nikki didn’t like was the taste of my cum, Diane said she had never tried it but wanted to try it with me. I told her she would need to kneel on the floor and look me in the eyes as she sucked my cock, she eagerly clambered to the floor pulling my cock straight from her ass into my mouth, she moaned in pleasure as she tasted her ass on my cock and she looked up at me and begged me to cum in her mouth, that was enough to push me over the edge and my cock exploded inside her mouth, she gagged as I pushed my cock to the back of her throat. I pulled her to her feet, she had swallowed every drop. She wrapped her arms around me and I turned and lay her onto the bed. After a few minutes I looked at the clock and it was nearly 1.00 am. We both started to get dressed and there was an awkward silence for a couple of minutes. I turned to her and asked her how she felt, she said she felt like a weight had been lifted, she said she had fancied me for so long and couldn’t believe she finally plucked up the courage to seduce me, I said I meant how she felt about betraying our partners, she said that she didn’t care, she started to say something about Nikki but then paused and just said it would be our little secret. She noticed that the camera was still rolling and she gave me a wry smile and said you have more than enough insurance now. She asked if I could make a copy for her, I said I would email it during the week. We moved downstairs and sat back down in the living room, this time together on the couch and we sat and watched a late night film, she fell asleep and I moved over onto the other couch. I too fell asleep and it wasn’t until Nikkis taxi pulled up outside that I woke up. Diane was still sleeping on the couch when I opened the door to let Nikki in, I expected her to be a little drunk but she was fine. I told her me and Diane had shared a couple of bottles of wine and she was sleeping on the couch, Nikki looked in on her and said to me that she knew I wouldn’t be able to get rid of her. I said that Diane had told me some of the sordid details she had shared about me and she smiled and said that she liked to boast about me and told me to get Diane a pillow and blanket and leave her to sleep it off in the living room and she could go home in the morning. I made Diane comfortable and followed Nikki Upstairs, in bed Nikki turned to me and said that I was nice to have put up with Diane all night and that she loved me, I tried to feel guilty but I don’t it was just sex.
